The successful implementation of a data warehouse can bring major, benefits such as Better enterprise intelligence,cost-effective decision-making and Competitive advantage.
There are certain issues surrounding data warehouses that companies need to be prepared for. A failure to prepare for these issues is one of the key reasons why many data warehouse projects are unsuccessful.
1. Loading & Cleaning Data : There may be a need to cleanse the data, which is not getting validated by the transaction system. some experts have said that the typical data warehouse project will require companies to spend 80% of their time loading and cleaning data.
2. Data Data everywhere : The end-users may not know how to use the data, as they are so much into the existing reporting culture. As a result of this user may be interested to create various types of reports out of the data, however the data many not culminate into meaningful decision process. Data warehouse is very powerful solution to implement, however understanding the requirement of the user and creating the necessary report structure is important responsibility of the consultant.
3. Granularity problem – Sometimes the transaction system may not have the data at the lowest level.This may occur frequently in a data warehouse that is tailored towards products or customers.It is important to make sure that the information that is placed in the data warehouse is rich in detail.
